Ryan Ladd, Sarah E Smith, David J DiCaudo, Ramin Fathi, Shari Ochoa
TL;DR
A rare case of a pilar cyst on the hand highlights the variability in their presentation and diagnostic importance.
Contribution
Reports a unique case of a pilar cyst in an atypical location on the dorsal hand.
Findings
Pilar cysts can occur in areas with few hair follicles, such as the dorsal hand.
The case emphasizes the need to consider pilar cysts in differential diagnoses for hand tumors.
Abstract
Pilar cysts are common benign cysts of follicular origin that typically arise in areas of skin containing dense hair follicles such as the scalp. Here we describe a unique case of a young woman who was found to have a pilar cyst on the dorsum of her hand, a rather atypical location given the relative lack of pilosebaceous units. This case illustrates the variability in pilar cyst presentation and the importance of considering a pilar cyst in the differential diagnosis of a patient presenting with a tumor of the dorsal hand.
